I we are running voice application which stream UDP (RTP) packets for voice, I am investigation some strange issue where my ifconfig ens4 | grep error counter going up specifically overrun
If you see UDP send buffer error that counter is getting increase periodically, does that means my TX buffer is getting full?

overrun directly involve with high speed RX data where kernel can't process hard enough, i have increase udp buffer size also but still time to time overrun counter getting increased.
